To all whont it ntay concern:

Be it known that 1, PETER DOOLING, con-I tractor,of the village of Douglas, in the county of Renfrew,Province of Ontario,Ganada,have

invented a new and useful Ditching-Plow, of:

which the following is a specification.

My invention relates to improvements in ditching-plows; and the object of my inven-. tion is to devise a ditching-plow by means of to which a continuous ditch, trench, gutter, or

drain may be out at a single operation, a further object being to make such a machine adjustable for digging ditches ofdiiferent depths and also to construct theplow in such :5 a way that it may be quickly and easily moved from place to place; and it consists, essentially, of a curved plowshare for throwing up the earth from the ditch, said share being secured to suitable plow-beams and mountedon a suitable frame provided with wheels, means being provided for altering the posi-' tion of the plowshare to bring it either into position for use or for moving from place to. place, means being also provided for steering :5 the plow and for varying the depth of the ditch which is being out, further means being provided for throwing aside the earth removed from the ditch'and suitable knives being provided for cutting the sides of the ditch, the various parts being constructed and arranged in detail, as hereinafter more particularly described. Figure 1 is a perspective view of my ditching-plow in position for being moved from place to place. Fig. 2 is a plan view of my ditching-machineinpositionforwork. Fig.3 is a vertical longitudinal section through the plow on the line X X, Fig. 2, when in the position for work. Fig. 4 is a preferable form 0 of knives for cutting the sides of the ditch. Fig. 5 is a section through the plow-beams and plowshare on the line Y Y, Fig. 3.

In the drawings like characters of reference indicate corresponding parts in each figure. A represents the front wheels, and B are the rear wheels, of the plow. The front Wheels A are journaled on a substantially crankshaped axle comprising the vertical parts a a. and the horizontal part a 1) is the axle for the rear wheels, which is also in the form of a double crank comprising theend pieces I) b and the cross-piece b the wheels B beingjournaled on short outwardlyezgtending portions 5 b O is a plowshare which is formed, preferably, of sheet metal and is secured at its sides to theside plow-beams D D. A central plowbeam E is provided, and the plowshare O is secured to this central beam by suitable means, the means which I employ being hereinafter more particularly described. The plowsh are curves first in a general rearwardly direction, then in a downwardly direction, and finally runs into a straight downwardly and forwardly slanting portion 0, and a central ridge 0 is formed thereon to throw aside the earth which is being loosened from the ditch being on t. The cutting edge at the lower end of the plowshare is preferably formed of a piece of specially-hardened steel 0 This cutting edge may be curved or straight or of any other suitable form; but the cutting edge which I prefer to use is provided with flat side portions 0 c and a central depression 0 the object of this being to out a channel along the center of the bottom of the ditch, so as to leave a higher, and consequently drier, portion at each side thereof, and thus a person working in the ditch may stand on the higher portion without getting wet, and, further, if pipes are to be laid in the ditch they will immediately assume the straight central posi- .tion.

Suitable knives F F are provided for cutting the sides of the ditch, and these knives are suitably bolted or otherwise secured at their lower ends to the lower portion of the side plow-beams and at their upper ends to the upper and forward portion of the said side plow-beams. When the earth in which 0 the ditching is being done is comparatively loose and free from roots or other obstructions, the form of knife used will. have .a straight cutting edge; but where it is necessary to break the earth to a certain extent the 5 form of knife is as shown in Figs. 1 and 3, in which the edges are indented, and portions thereof are bent up to form the horizontal cutters ff.

G G are moldboards of any suitable form,

' ent ways, if found preferable.

which are secured to the side plow-beams D D by the following means: Slotted hangers g g are secured by bolts 9 q to the inner side of the plow-beamsD D. Bolts or thumb-screws g pass through the slots g into the blocks 9", which are in turn suitably riveted or otherwise secured one to each of the moldboards G. Bolts g 'pass through the lower portions of the moldboards and the side plow-beams, and thus the moldboards are securely fastened to the plow-beams, but are allowed a certain amount of swing in a vertical sense. The moldboards G G may be braced together by a rod g secured by a nut at one end to the moldboard G and by a nut at the other end to the moldboard G.

I will now proceed to describe the means provided for raising and lowering the plowshare to bring it into position for work, to adjust the depth of the ditch, or to raise it entirely above ground for moving from place to place.

The central plow-beam E is secured to the side plow-beams D D by means of suitable ribs e e, the said ribs being secured to the central plow-beam and to the side plow-beams by suitable bolts.

H is a connecting member having upwardly-bent ends 71 h,which are suitably bolt ed to the side plow-beams D D. A screwshaft 1, provided with a hand-wheel 0 is socured to the connecting member H, preferably by a ball-and-socket joint, which maybe of any suitable form; but the form which I have adopted is as follows: In the central portion of the connecting member H a semicircular depression k is formed. A cap J is provided having a corresponding semicircular depression in its under side and a hole from said depression through the upper portion of the said cap. The lower portion of the screwshaft, on which is a ball, is inclosed in the said depression between the connecting member H and the cap J.

K is a threaded bearing for the screw-shaft I and is suitably bolted or otherwise secured to the horizontal portion a of the doublecrank-shaped axle A. This, however, is only one of the ways in which the threaded bearing for the screw-shaft may be formed, and I might employ any one of several other differ- It will now be seen that by turning the screw-shaft I the plow-beams, plowshare, knives, and moldboards will be lowered into a position for work, as shown in Figs. 2 and 3, or may be raised therefrom when it is desired to move to a difierent place.

My device isprovided with a central forward V-shaped colter L, the lower portion or angle of the V extending down to about half the depth of the ditch which is being dug, and the upper portion of the V is secured to the side plow-beams by any suitable means, such as clevises Z Z. The frame of the rear portion of the machine consists of a double beam M, comprising the two halves M M These beams, commencing at their rearward ends, consist of the forwardly-extending horizontal portions m m, the vertical portions m m the forwardly-extending portions m m the converging portions m m the downwardly-sloping portions m m the long horizontal portions m m, and the downwardlycurved portions m m these downwardlycurved portions embracing between them the rear end of the central plow-beam E, and a bolt e passes through the portions of said double beam and through the rear of the central plow-beam, pivotally securing them together. The halves of the double beam M are separated by blocks N, and cross-pieces O O O extend between the horizontal portions m m and are bolted thereto. In order to secure the moldboards G G to the double beam M, angle-irons P P are secured to the moldboards, and to the angle-iron P a bar 19 is pivotally secured. The bar 19 overlaps the harp and both rest upon the double beam M. Suitable yokes or covers 19 19 are screwed to the beams, and a bolt 19 passes down between the yokes 19 19 and between the two portions 071* m of the double beam, and passing through holes in the bars P P hold the said bars in any desired position to which they may be adjusted.

It may here be mentioned that the upright portions m m of the double beam M are pivotally secured to the portions b b of the crank-axle b by means of suitable pivotal bolts or pins R R.

S is a lever which is rigidly and strongly secured to the horizontal portion 29 of the rear axle. A segment 8 of any suitable form is secured to the rearwardly-extending bars, which is supported by and bolted to the crosspieces 0 O 0 A spring-bolt 3 provided with a connecting-rod and finger-grip of ordinary form, is slidably secured to the lever S and is designed to engage the teeth or detents of the segment 8, and thus hold the rear axle in the position shown in Fig. 1, in which the rear portion of the machine is raised, or in the position shown in Figs. 2 and 3, in which the rear portions of the machine are lowered into position for work, or in any intermediate position.

T is a draw-bar of suitable form and is secured by suitable means to the upright portions d d of the plow-beams D D, and the means for drawing the plow is suitably attached to the said draw-bar.

U U are braces extending from the upright portions d d of the plow-beams to the top of the forward axle and are suitably secured thereto. Screw-swivels u, u are provided on said braces for the purpose of lengthening or shortening them, according to the position of the plow.

Braces V V extend from the lower portions of the forward axle to the upright portions (1 d of the plow-beams and are secured to said ITO upright portions and to said forward axle by suitable means. On these braces screwswivels o v are also provided, whereby the said brace may be lengthened or shortened.

W W are braces secured at their forward ends to the upright portions cl (1 of the plowbeams and at their rearward ends are secured by bolts to w to the curved portions of the plow-beams. Eyes 10 w are formed on the rear extremities of the braces W W, and braces 2 3 are secured at one end in the said eyes and at their opposite ends are secured in eyes formed, preferably, in the horizontal portions on m of the double plow-beam M. These braces are also provided with screw-swivels 4 5. Afgrass-cutting colter 6 of suitable form is secured to the draw-braw I by means of a suitable bolt 7. the plowshare to the plow-beams where the plowshare has the central ridge 0. The fiat portion of the plowshare o is secured to the side plow-beams by suitable angle-irons 9.

It will now be seen that I have accomplished the objects which I had in view in devising a ditching-plow, for the plow which I have devised will at a single operation cut a clean ditch as deep as is necessary, throwing aside all the earth removed therefrom, and when the Work at any particular place is completed the plow may readily be raised above the level of the earth, and the machine may then be moved to any other place and recommence work with a minimum loss of time.

It will of course be understood that certain variations in the details of my device may be made without departing from the spirit of my invention. For example, the eyes shown for securing the ends of the braces U U V V to the forward axle may be dispensed with and other connections used. Similarly the means of connecting the knives F F to the plowbeams may be changed, if desired; also, their exact shape may be varied. The lever and segment 8 for raising and lowering the rear portions of the machine might be dispensed with and other suitable means employed in their stead. I may further point out that although the braces 2 and 3 are secured at their rearward ends to the portions M M of the double beam they might be secured, if desirable, to the cross-bar O in order to permit of the rear crank-shaped axle being turned completely around. It may further be mentioned that the position of the various parts of the machine relative to each other might be considerably changed. For example, the point of the plow as shown is considerably ahead of the center line of the front wheels; but in order that the depth of the ditch should be kept perfectly even I might arrange the machine in such a way that this point will come directly in the center line of the front wheels.
